Patients with itchy lymph nodes have the following common causes: a. When female patients apply more cosmetics, they can have allergic allergic reactions due to their own allergic constitution, causing superficial lymph node enlargement and itching symptoms. Patients need to remove allergens as soon as possible and take anti-allergy drugs such as paracetamol or loratadine orally. For patients with mild allergy, the itchy superficial swollen lymph nodes can subside on their own after 48 hours. Second, the swelling and itching of lymph nodes can be caused when there is infection in the patient’s body. Patients should take oral amoxicillin and levofloxacin tablets to strengthen anti-infection treatment, and apply Ruyi Jinhuang cream and ichthyolipid ointment to the swollen lymph nodes to promote faster absorption of inflammation in the body, and the symptoms of itchy lymph nodes can be gradually relieved after the inflammation subsides without serious infection.
